Unable to run terragrunt validate with remote_state init

[fproulx-boostsecurity]

Expected Behavior

I expect that I can run terragrunt run-all validate in disable_init = true mode

Actual Behavior

I get an error saying that GCS backend must be init

 Error: Backend initialization required, please run "terraform init"
│
│ Reason: Initial configuration of the requested backend "gcs"
│
│ The "backend" is the interface that Terraform uses to store state,
│ perform operations, etc. If this message is showing up, it means that the
│ Terraform configuration you're using is using a custom configuration for
│ the Terraform backend.
│
│ Changes to backend configurations require reinitialization. This allows
│ Terraform to set up the new configuration, copy existing state, etc. Please
│ run
│ "terraform init" with either the "-reconfigure" or "-migrate-state" flags
│ to
│ use the current configuration.
│
│ If the change reason above is incorrect, please verify your configuration
│ hasn't changed and try again. At this point, no changes to your existing
│ configuration or state have been made.
